I'm planning to get an HTC One M8 tomorrow (Sunday). I recently came across the following tip:

From what I've read the HTC One M8 and Sense 6 are already extremely responsive and without lag, so I don't know how much this would really improve M8 performance compared to other phones. An added bonus regardless is apparently increased battery life. For those that don't want to take time to read the article here is a summary of the important part. In Android 4.4 go into Settings -> About Phone ->Build number and tap the build number 7 times. Select "
Select Runtime" and change
Dalvik to
ART. Reboot and apparently you'll have increased speed.
Obviously since I don't have the phone yet I can't confirm it myself.
Anyone want to test it, and report on the results?
Edit: I used Dalvik for half a day when I got my new phone, and then decided to test out ART. Its worked great for me so far. I haven't come across any apps that its incompatible with, and I've used the phone for three days without needing to recharge it. (I might be able to get 4 days out of it, but I'll probably plug it in tonight when I go to sleep just to be on the safe side).
